I was there for 40 minutes the other day waiting to buy a single block of cheese. People waiting in line in front of me with their giant Costco carts piled high to the ceiling. You think any of those people would offer to let me go ahead of them? Not in a million years. The most selfish self absorbed people in the world shop at Costco. Over at Winco with their self check out machines, I would've been in and out of there in 5 minutes, but it's $5.98 for two pounds against $4.18 for one pound at Winco.
